Now you'll create a more generalized concatenation function using the two functions Lisp is famous for: car and CDR.
现在您将使用两个著名的Lispcar和cdr函数创建更通用化的concatenation函数。
These functions do string copying and concatenation, but in a much less error-prone way. These functions' prototypes are.
这些函数执行字符串复制和拼接，不过更不容易出错。
The following example prints a combination of a local variable, system functions, and a text string using concatenation.
下面的示例使用串联打印局部变量、系统函数和文本字符串的组合。
Besides the typical PID controlling method, concatenation, feedforward and fuzzy control algorithms are used. As the result, the control functions of the system are efficiently improved.
在控制软件方面除采用经典的PID控制外，还引入了串级、前馈及模糊控制等算法，有效地提高了系统的控制性能。
